This is when someone lacks the social skills that normal people developed in high school. They missed out on normal socialization because they were outcasts, more than likely because they were physically unattractive, but that is not always the case. Attractive people can be affected by this when they are only liked BECAUSE of their looks and nothing else. Usually occurs in males. Excessive internet use is also a dominant cause.

So I met a boy and I was trying to hang out with him:

me: Hey, since we only hang out at bars, how 'bout you go to this thing with me?

him: I'm going to that with my friends April 7th!

. . . . .
(Silence)

me: Okay, well I hope you guys have fun.

If he wasn't into me, this would have just been an asshole move, but apparently he WAS into me and just a fucking idiot because now he's my boyfriend.

P.S. Even when I brought up how socially retarded that was he still did not invite me.

Individuals who suffer from social retardation usually make a fool of themselves by emitting awkward vibes to the people around them. Socially retarded people are usually fat and ugly. They are often pale from staying inside, away from other people.
